PPR plastic fitting reducing elbow is a hot melt pipe fitting made of random copolymer polypropylene material, which is characterized by realizing the composite function of pipe turning and diameter reduction. This product optimizes the layout efficiency of conventional piping systems by combining material science with fluid dynamics.
PPR plastic fitting reducing elbow is an integral injection molding of conical reducing section and elbow arc part of integral structure, which can reduce the leakage risk of metal pipe welding flange. Gradual inner wall design maintains laminar flow state and avoids vortex energy loss caused by abrupt contraction structure. Traditional split metal reducer solutions require additional steering joints, increasing system complexity.
Hot melt connection advantage Pipe and pipe fittings in the molten state to achieve molecular chain interpenetration, after cooling to form a homogeneous connector. This molecular level combination eliminates the leakage hidden danger caused by the aging of the rubber seal ring, and the connection strength exceeds the parent metal body. There is stress concentration zone in metal thread connection, and the sealing performance decreases after repeated thermal cycles.
PPR plastic fitting reducing elbow inner wall smoothness reaches the level where microorganisms cannot adhere, preventing biofilm breeding in water delivery system. The inert characteristics of materials do not participate in electrochemical corrosion, solving the problem of galvanic effect of metal pipes when dissimilar materials are connected. The curvature radius of transition section is optimized by fluid simulation, and the local drag coefficient is lower than that of conventional design.
